Tahuri Opus Tuhinga o mua AIFF

Mā te pūmau, ā, ka noho te pūmau, ka mau te mokatere tauira taketake (44.1 kHz, 48 kHz, ērā atu mea) ki te huaputa AIFF.

He — ko te reo kore ngaro he 5-10x nui ake i te oro oro i te āhuatanga ōrite. Ka whakaritea mō ~10 MB ia minu mō AIFF e ōrite ana ki ~1 MB ia minu mō te bitrate tiketike OPUS.

He — e rokiroki ana ngā kāwai kore ngaro i ia huaputa. E tūmanako ana ko te AIFF kia 3-8x te rahi o te OPUS. Ko te painga kāore he ngaro atu o te āhuatanga i te whakarerekētanga, i te whakakōrero rānei.

Kāore, ā, e tika ana kia mārama: kāore e taea. Ko te OPUS kua whakakoretia te taipitopito i te wā o tōna waehere taketake, ā, ko te whakaroa i te mea e noho ana i roto i tētahi AIFF kāore i te ngaro, ka pupuri tonu - kāore anō. He maha ngā wā e nui ake ai te faila, ā, he ōrite ngā pūoro. He mahi tika tonu tēnei i mua i te whakarerekētanga, nā te mea kāore e tāpiri te AIFF i tētahi whakatupuranga tuarua o ngā ahanoa i te wā e kawea atu ai. Ko AIFF te āhua o te whakawhitinga whare taupuni i runga i te macOS, e whakahaere tika ana i te metadata i te WAV noa iho, ā, ka tāurutia ki Logic me Pro Tools. Kua tata tonu te kore e tautokona e ngā pūrere takitahi te Opus — e whakaaro ana ki te whakatangitangi pūmanawa anake, ā, e tūmanako ana ngā pūkōrero waka kia whakakāhore i a ia.

He pūrere me te orooro i roto i a ia, kaua ko te orooro i tōna ake. Ko taua apa tāpiri ko te wāhi e pupuritia ai te roanga, te taupū rapu me ngā metadata e tautuhia ana e te āhua, kia mōhio ai te kaitapere ki te roa o tētahi AIFF i mua i te whakakōrerotanga o tētahi tāruatanga kotahi, kaua e whakataki i te faila katoa hei kitea. Ko te tikanga hoki kāore te whakaroatanga i te whakatau i te mea e āhua nei: he maha ngā pūrere o tēnei momo e whakaaetia ana kia nui ake i tētahi momo orooro, ko te take e rua ai ngā pūkete AIFF ka rerekē te whanonga i te wā e kitea ana i waho. AIFF e rokiroki ana i te PCM nui-tangata kāore i whakawhāitihia - te ōritetanga Apple-ā-rohe o WAV, me te ōritetanga iti-ki-iti.

Mai i te Wīwī, ā, ko te nuinga o te wā mai i ngā pūmanawa, ehara i te mea mai i ngā pūrere. I hangaia te OPUS mō te whakawhitiwhiti me ngā mekameka utauta pūtake-whenua, nō reira ka puta mai i roto i ngā rawa kēmu, ngā pūkete whakataki, ngā pūkōrero podcast me ētahi atu mea i hangaia e ngā tāngata kāore e hiahia ana ki tētahi kōrero ā-whakahaere. Ko te mea kāore e puta mai i roto ko ngā pūrere hiko, ko te take noa iho e hiahiatia ana e tētahi te tahuri i tētahi. Ko Opus he paerewa IETF mai i te tau 2012 nāna i whakakotahi te pūrere kōrero SILK o Skype me te pūrere pūoro CELT o Xiph ki roto i tētahi hoahoa.

He, kāore he āhuatanga e hiahiatia ana kia māharahara. He tūmatanui te whakaahuatanga, ka taea e tētahi te whakatinana i tētahi kaituhi, i tētahi kaituhi rānei me te kore e pānui, ā, kāore e taea e tētahi te huri i ēnei whakaritenga i muri mai - ko te take e puta ai i roto i ngā utauta pūtake-tūwhera, i ngā mīhini kēmu me ngā wāhi katoa ka whakamutua te kaupapa e te whakawhitinga ā-ara. Kāore te tahuri i te whakarerekētanga; ko ngā pūkete kua noho tika kētia e koe hei whakamahi.

Mō tētahi pūranga whaiaro, ā, mō ētahi mea e tuku ana ki tētahi atu, e whakaaro ana e rua. AIFF e angitu ana te angitu i te wā e kore e whakarerekētia ana — ko ngā mea katoa e tākaro ana i tēnei rā ka haere tonu te tākaro i a ia — engari ko ngā kaikōrero hou me ngā pūrere hōu e nui ake ana te pūmau ki tōna whakakapi, e mahi ana i te mahi ōrite. Mēnā me whakatuwhera te faila i runga i tō tātou mīhini, he pai. Mēnā me whakatūria i runga i tētahi pūrere i hoko i roto i te rima tau, ka kōwhiria te mea hou ake. He nui tonu te AIFF ki te WAV me te tautoko iti iho i waho o te ao Apple, nō reira he kōwhiringa iti mō te tuaritanga.

Ko ngā tāurunga ā-whakaahua kua whakawhāititia i te pūtake nui; ko ngā pūkete wātea i whakaingoatia e whiwhi ana i tētahi taumata tiketike ake, ā, kāore he tepe-tokotahi o ngā pūkete Pro. Ko te pūmahara whakahura te āhua o te āhua o te āhua o te whakawhāititanga i mua i te whakawhāititanga o tātau tauwāhi pāpāho.

He. He maha ngā pūkete OPUS i roto i tētahi tāpiritanga — ka whakamātautau te whakarerekē i a rātou i te taha kotahi, ā, ka hoki mai i tētahi ZIP o ngā hua AIFF. Kāore e hiahiatia kia tāpiri anō te hipanga tāpiritanga mō ia pūkete.

Ka tangohia ngā pūkete AIFF me ngā pūkete i whakarewatia i muri i tētahi matapihi takahuri poto. Kāore e tirotirohia, e tiritiritia, e whakaakona rānei i ngā pūkete o te kaiwhakaari. Ko ngā pātahitanga whakatere tūturu he wā-whāiti, ā, e hono ana ki tō tātau hautanga.
